Technical Field

[0001] This utility model relates to the field of polyurethane roller technology, and in particular to a polyurethane roller that is easy to assemble. Background Technology

[0002] Polyurethane rollers are wheels made of polyurethane, a polymer material between rubber and plastic. It has the elasticity of synthetic rubber and the rigidity of plastic, making it suitable for applications requiring cushioning and wear resistance. Polyurethane rollers are widely used in various equipment, such as office chair casters, hospital stretcher casters, conveyors, printers, and film packaging machines. They are suitable for parts that require repeated friction and pressure.

[0003] When workers need to transport electroplated products, they install polyurethane rollers on the drive unit of the transport equipment. However, the installation process for existing polyurethane rollers usually requires workers to remove the entire rotating rod from the drive unit of the transport equipment, which wastes a lot of time and causes inconvenience. Utility Model Content

[0004] The purpose of this invention is to solve the problem of inconvenience for workers when installing polyurethane rollers in the prior art, and to propose a polyurethane roller that is easy to assemble.

[0006] Preferably, the surface of the metal ring is provided with a disassembly device, the disassembly device including an anti-slip groove, the anti-slip groove being formed on the surface of the metal ring, and a limiting rod being fixedly connected inside the anti-slip groove. The anti-slip groove can cooperate with the metal ring and the limiting rod to achieve the purpose of storing the anti-slip strip.

[0007] Preferably, an anti-slip strip is fixedly connected to the inner side of the rubber ring, the anti-slip strip is inserted into the inside of the anti-slip groove, the anti-slip strip is sleeved on the surface of the limiting rod, and the anti-slip strip can cooperate with the rubber ring to achieve the purpose of supporting the anti-slip strip.

[0008] Preferably, a baffle is placed on one side of the metal ring, and the baffle is placed on one side of the anti-slip strip. The baffle can cooperate with the metal ring to restrict the anti-slip strip.

[0009] Preferably, a positioning hole is provided on one side of the metal ring, and a protrusion on one side of the baffle is inserted into the interior of the positioning hole. A threaded rod is fixedly connected to one side of the metal ring, and the baffle is sleeved on the surface of the threaded rod. The positioning hole can cooperate with the metal ring to achieve the purpose of restricting the baffle.

[0010] Preferably, the threaded rod is threaded with a nut, which is placed on one side of the baffle plate. The nut can cooperate with the threaded rod to restrict the sliding of the baffle plate.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] In this invention, by setting up an assembly device, when a worker needs to install a polyurethane roller, the worker places two metal rings on a rotating rod. The metal rings drive a rubber ring, which in turn pushes a stabilizing block. The stabilizing block is inserted into a receiving slot. The worker then pushes a rotating ring, which in turn pushes a first threaded ring. The first threaded ring is inserted into a receiving slot. The worker then rotates the rotating ring, which in turn drives the first threaded ring. The outer surfaces of the first threaded ring and the second threaded ring are threadedly connected. By setting up the assembly device, the worker can effectively and conveniently install the polyurethane roller, avoiding the waste of a lot of time when installing the polyurethane roller, and thus reducing the inconvenience encountered when installing the polyurethane roller.

[0013] In this invention, by setting up a disassembly device, when a worker needs to replace an aging rubber ring, the worker uses an auxiliary tool to turn the nut, causing the nut to disengage from the threaded rod. The worker then removes the retaining plate from the threaded rod, freeing the retaining plate from its restraint on the anti-slip strip. The worker then pushes the rubber ring, causing it to pull the anti-slip strip away from the anti-slip groove and the limiting rod. The worker then removes the old rubber ring and installs a new rubber ring on the metal ring. The above steps are then reversed. By setting up the disassembly device, it is possible to effectively and conveniently replace aging rubber rings, avoiding time-consuming situations and thus improving the worker's work efficiency.

A first threaded ring 32 is placed inside the receiving groove 33. The first threaded ring 32 is threadedly connected to the outer surface of the second threaded ring 35. A rotating ring 31 is fixedly connected to one side of the first threaded ring 32. The rotating ring 31 is placed on one side of the metal ring 1. A stabilizing block 34 is fixedly connected to the inner side of the metal ring 1. A stabilizing component is provided on the outer surface of the rotating rod 5.

[0024] Specifically, the stabilizing component includes a storage port 36, which is opened on the outer surface of the rotating rod 5. The stabilizing block 34 is inserted into the inside of the storage port 36. The storage port 36 can cooperate with the rotating rod 5 to achieve the purpose of storing the stabilizing block 34.

[0025] Specifically, the surface of the metal ring 1 is provided with a disassembly device 4, which includes an anti-slip groove 41. The anti-slip groove 41 is formed on the surface of the metal ring 1, and a limit rod 42 is fixedly connected inside the anti-slip groove 41.

[0026] In this embodiment, the anti-slip groove 41 can cooperate with the metal ring 1 and the limiting rod 42 to achieve the purpose of storing the anti-slip strip 46.

[0027] In this embodiment: an anti-slip strip 46 is fixedly connected to the inner side of the rubber ring 2. The anti-slip strip 46 is inserted into the inside of the anti-slip groove 41. The anti-slip strip 46 is sleeved on the surface of the limiting rod 42. The anti-slip strip 46 can cooperate with the rubber ring 2 to achieve the purpose of supporting the anti-slip strip 46.

[0028] Specifically, a baffle 44 is placed on one side of the metal ring 1, and the baffle 44 is placed on one side of the anti-slip strip 46.

[0029] In this embodiment, the baffle 44 can cooperate with the metal ring 1 to restrict the anti-slip strip 46.

[0030] Specifically, a positioning hole 47 is provided on one side of the metal ring 1, and a protrusion on one side of the baffle 44 is inserted into the interior of the positioning hole 47. A threaded rod 43 is fixedly connected to one side of the metal ring 1, and the baffle 44 is sleeved on the surface of the threaded rod 43.

[0033] Working Principle: By setting up the assembly device 3, when the worker needs to install the polyurethane roller, the worker places two metal rings 1 on the rotating rod 5. The metal rings 1 drive the rubber ring 2, which in turn pushes the stabilizing block 34. The stabilizing block 34 is inserted into the receiving slot 36. The worker then pushes the rotating ring 31, which in turn pushes the first threaded ring 32. The first threaded ring 32 is inserted into the receiving groove 33. The worker rotates the rotating ring 31, which in turn drives the first threaded ring 32. The first threaded ring 32 is threadedly connected to the outer surface of the second threaded ring 35. By setting up the assembly device 3, the worker can effectively and conveniently install the polyurethane roller, avoiding the waste of a lot of time during installation and reducing the occurrence of problems during installation. To address the issue of convenience, the disassembly device 4 is installed. When the worker needs to replace the aging rubber ring 2, the worker uses an auxiliary tool to turn the nut 45, which disengages from the threaded rod 43. The worker then removes the retaining plate 44 from the threaded rod 43, freeing the retaining plate 44 from the anti-slip strip 46. The worker then pushes the rubber ring 2, which in turn moves the anti-slip strip 46, disengaging it from the anti-slip groove 41 and the limiting rod 42. The worker then removes the old rubber ring 2 and installs the new rubber ring 2 onto the metal ring 1. The steps are then reversed. By installing the disassembly device 4, the worker can easily replace the aging rubber ring 2, avoiding time-consuming replacements and thus improving work efficiency.
